When looking up this album on social media, I came across a comment which suggested that by this point, Egypt had already been conquered for 500 years. IIRC it was first the Kush, then the… Babylonians? and finally Alexander’s (and Ptolemy’s) Greeks.
More like 700 years. Egypt was conquered by Kush in 712 BCE. In 671 BCE the Assyrians came and took over. The Egyptians rebelled successfully and kicked them out in 653 though. The next conqueror who attacked Egypt was Persia in 525, the conquest was finished in 341. Persian rule lasted until Alexander the Great took Egypt without resistance in 331. After Alexanders death his generals divided the empire among each other, thereby forming the Diadochi kingdoms. Ptolemy got Egypt and founded the dynasty that ended with the famous Cleopatra in 30 BCE when she died and Egypt was incorporated as a roman province.
This is hard, I either did not read those series or I read them like twenty-thirty years ago! All I can guess is Nr 2 might be the Professor, Nr 8 one of the Daltons and Nr 10 maybe Pirlouit\Peewit\Pfiffikus because there is his goat in the last panel.
